To all whom z't may concern:

Be it known that I, BENJAMIN J. DRYER, a citizen ofthe. United States,and a resident of the. city" of New York, borough of -Manhattan, in thecounty and State of New York, have invented a new and ImprovedResilientW heel, of which the following is a full, clear, and exactdescription.

This' invention relates to resilient wheels of the type havingnon-deformable -treads, and the resiliency is, obtained by means ofpneumatic balls positioned between the inner section of the wheel andthe outer tread section so as to absorb the shocks and take up thethrust impartedtothe tread section.

The invention has for its general objects I to improve and simplify theconstruction of wheels of the character referred to so as to be reliableand efficient in use, comparatively inexpensive to manufacture and keep1h op-' equipped with such wheelsis rendered pos-' siblel- .With suchobjects in .view, and others which will appear as thedescriptionproc'eeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth withparticularity in the following description and claims appended hereto.f.

' In the accompanying drawings, which illustrate oneembodimnt of theinvention, and wherein similar characters of reference indicatecorresponding parts in all the vlews,

Figure 1' is'a side view of a wheel with portions broken away and insection, wherein the pneumatic balls, are yoked respectively to theinnerand outer sections of the wheel;

A Referring to the drawing, the pneumatic balls C areyoked to the inner and outer I sections A nd B of the wheel by a type of'truss arrangement, whereby thrusts and strains applied in; anydirection will be effectively cushioned.

method of operationwill be readily under stood by those skilled in theart to which the invention appertains, and while I have described theprinciple of operatiom together with the structure which I now considerto -be the best embodiment thereof, '1 desire to have it understood thatthe structure shown is merely illustrative, and that suchichanges Y 'maybe made when desired as arew-ithin the scope of the appended claims.

Having thus described my invention, I
